[Ubuntu 18.04 LTS] Quartus Prime Platform Designer HDL generation fails with Can't locate Getopt/Long.pm in @INC (you may need to install the Getopt::Long module) (@INC contains:

[GApts]

OS: Ubuntu 18.04 LTS. Clean installation.

I tried adding

export PERL5LIB=/home/giorgi3092/intelFPGA_lite/19.1/quartus/linux64/perl/lib/5.28.1

to ~/.bashrc but problem persisted.

Error messages:

My bad.

I was in the wrong directory while executing commands at http://www.armadeus.org/wiki/index.php?title=Quartus_installation_on_Linux#Perl_Getopt::Long

Followed it, and problem solved.
